A train goes at a constant speed. If it covers 150 miles in 2 1 2 hours,
What distance would it cover in 7 hours?
Answer: I think is 420 miles in 7 hours
hope this helps :D
Step-by-step explanation:
Answer:
A train would cover 180 miles in 3 hours, So in 6 hours it will cover 360 miles, in 7 hours it will cover 420 miles.
Step-by-step explanation:
150 miles → 2 1/2 hours = 150 minutes
x miles → 3 hours = 180 minutes
(150 × 180) ÷ 150 = x miles
27,000 ÷ 150 = x miles
180 = x miles

A line contains the points (82, −96) and (87, −86).
What is the slope of the line in simplified form?
Enter your answer in the box.
Answer:
The answer is 2Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(82, −96) and (87, −86)
We have
[tex]m = \frac{ - 86 - - 96}{87 - 82} = \frac{ - 86 + 96}{5} = \frac{10}{5} = 2 \\ [/tex]
We have the final answer as

The soccer team and the American football team are sharing the field for their practices today. The
soccer team meets for practice every 2 days, and the American football team meets every 4 days. How
many days from now will they have to share the field again?
Answer:
4
Step-by-step explanation:
We can find the LCM of the 2, being 4.
Answer: 4 days later
The soccer team goes every two days. The American football team goes every 4 days.
After one time of soccer practice, next time the football team will be there.
The football team goes every four days, so after one day of soccer practice, the Football team has to share the field.
